nun-earn.

Be it known that I, ALFRED W. KNUTSON, a citizen of the United States,residing at Galesburg, inthe countyof Knox and State of Illinois,have'invented certain new and useful Improvements in End-Gates; and I dohereby declare that the following is a full, clear, and exactdescription of. the invention, which will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to end gates for wagons-particularly, however, tothat type which closes the end of the wagon andwhich has an openingcovered by a panel or closure and movable withrespect to it.

The main object of the invention is to provide an end gate ofthisdescription having an opening extending below the upper surface of thebed of the wagon body and not covered by any parts that would interferewith the free passage of materials from the wagon 'body, or such aswould interfere with shoveling operations, there being a guide or'guides upon the end gate at said opening to' receive and guide the panelor closure at its lower extremity, said guides maintaining the panel inits proper position.

Another object is to provide an end gate or shoveling board adapted tobe brought down to the open shoveling position, including an opening;for the reception of a panel or' closure, which, in the closed orvertical. position of the gate, is adapted for exposing said opening toany desired extent for the discharge of material without swinging fromits position at said opening.

Another object is the-construction of a wagon body and end gate wherebymaterials that maylodge on parts of its rear end and that might preventthe proper seating of the panel can be readily discharged.

Besides the above objects the invention relates to other certain detailsof construction which will be more particularly pointed out in thefollowing specification, aided by the accompanying drawings, in which,

Figure 1 is an elevation of the outer surface of the end gate orshoveling board; Fig. 2 is a longitudinal section of a portion of thewagon body, and the end gate or shoveling board, the latter being shownin its open'position;

position, together with the panel portion shown in an open position atright angles to the plane of said end gate;

Fig. l is a section of a part of the board and wagon body on line H,Fig. 1, the parts being much enlarged over that in Fig. 1;

Fig. 5 shows, in perspective, one of the parts of my structure;

Fig. 6 is an elevation of certain guide members and the parts to whichthey are se cured;

Fig. '7 shows the edge of a portion of the shoveling board and a pivotedguide thereon for carrying the panel;

Fig. 8 shows the same, in perspective, on a larger scale;

Fig. 9 is a slight modification of that form shown in Figs. 7 and 8;

Figs. 10 and 11 are details of certain pivoted members shown in Figs. 78 and 9;

Fig. 12 is an elevation of the outer side of a modified form of an endgate from that shown in Fig. 1;

Fig. 13 is a sectional elevation of the same on line 13-13 of Fig. 12;

Fig. 14 is a view of the inner or opposite side of the board from thatshown in Fig. 12;

Fig. 15 shows, in perspective, the form of the device shown in Fig. 12in the open position of the panel; and,

Fig. 16 shows, in perspective, the construction of certain detachedparts.

In the first eleven figures 1 indicates the sides of the wagon body, 2the bottom or bed thereof, 3 any usual sill beneath the bot tom or bedas its rear edge, and a an additional member bolted thereto as clearlyshown in" Fig. 4, there being a series of openings 5 in the latterthroughout its length shown partially in Fig. 16, the purpose of whichwill be disclosed later.

I do not claim broadly the relation of the movable closure or panel inan end gate but the combinations with certain structures that yieldadvantages to be named herein.

Fig. 3 thereby giving a clear working space upon the bed between theportions 6 so that materials within the'wagon box may be easily andreadily discharged and also that the shoveling operation willnot beinterfered wlth as stated earlier herein, there being no partsextending. across such opening.

9 indicates an ear secured to each side of the body 1, see Fig. 2,wherem but one 1s shown, and 10 are rods loosely attached at one end toeach. 11, ll are keepers secured to the portions 6 through which theears 8 purpose in practice. 12 indicates a block secured to each portion6 upon each of which is secured a plate 13 each having a free edgeextending-in the direction of the other, the plates at said edges beingspaced from the portions 6 as clearly shown in Figs. 8 and 1, but saidedges do not extend opposite the opening. This is clearly shown inFig. 1. The lower ends of the plates are bent inwardly at right anglesat 14 and secured to them in any desired manner is an angle bar 15, seeFig. 4. The ends of the angle bar are secured to the portions 6 in anyapproved manner, bolts 16, for, example, as shown in Fig. 4. This anglebar and the cross member 8 previously described serve to create a rigidframe structure with the portions 6. Y

17, 17 aremembe-rs secured to said portions 6, each being slotted asshown in Fig. 5, at 18, to receive the edge of the plates 13 into them,but this, it must be understood, is merely a preferred structure.

19, 19 are keepers secured to the members 17, for example, behind whichthe rods 10 are locked tomaintain the end gate in its closed position asin common practice. The relation of the angle bar 15to the bottom or bedof the wagon body is such as to leave a space between the end of saidbed and said angle bar within the opening between the portions 6 toreceive the closure now to be described. This comprises a panel 20adapted to lie within the opening of the end gate flush with the latter,suitably cross-braced by an upper and a lower angle bar .21, forexample, and secured to the portions 6 near each edge and near theirupper ends is an angle plate 22 shown in detail in Figs. 10 and 11, andpivoted thereto is an angle guide-plate 23, forming a support and guidefor said panel.

From the fact that the angle guide-plates 23 are pivoted as described,the said panel may be swung to any desired position and,

' of as shown in Figs. 8, 7 8' and 9. The cross member 8 limits thetilting of the panel and supports it in the position shown in Fig. 3,

when said panel is drawn far enough inward into the wagon box. When inthe vertical position or in the same plane with the end gate the lowerend of the panel lies between the angle bar 15 and-theend ofthe wagonbed 2. The space between the angle bar and said bed is just'?sufiicientto easily receive said paneland yet provide a tight closure sothat there can be no leakage of grain. ,When it is desired to permit theflow of material from the wagon body byligravit'y' the panel may .beraised to any. desired extent but the weight of the grain cannot forcethe panel outward at its bottom'since ret ained by the guides 13.Theendsof the lower angle bar 21 on the panel project beyond the edgesof said panel and engage behind the guides as clearly shown in said Fig.

.1, it being'understood that the edges of the panel lie close to'theedges of the portions 6 sothat there can be no leakage. of grain. Theangle plates 22-are 'let into a recess 23' in the edge of the saidportions 6 and the recess is deep-enough, also, to receive the outerlimbof the guide-plates 23 so that the edges of the said panel whenclosedwill fit closely against'the edges of said portions6.

' The openings 5' in the -member4 permit the material,-which wouldotherwise lie in therecess behind'the angle bar 15, tobe dischargedtherethrough so. as to permit" the panel to properly seat. When the endgate, including the panel,;is to be swung to the open position, Fig.Q'theangdebar 15itilts upon the member 4 naturally sliding forwardlythereon as the combined weight of the parts carries it toward the end ofthe wagon box. f 7

It is to be understood that while the arrangement described is thepreferred one,

equivalents .may be adopted with regard to any of the parts of theentire structure, it being my desire to provide in a combined end gateand closure means at the bottom of said end gate to permit the verticaladjust ment of the panel for governing the rate of discharge prior tothrowing the end gate down to the open or shoveling position whileretaining the panel in the same plane with said end gate.

In Figs. 12 to 15 inclusive .1 have shown a simple form of device whichvis suitable for certain purposes. I

25 indicates the side portions of the end gate and 26 the panelpivotally mounted as before by means of the plates27 and 28corresponding to 22 and 23 respectively of the toms orthe portions 25which together with the membersO which correspondto 8' of the otherfigures, forms a complete rigid frame for said end gate; r

The bottom of the panelv engages behind said member29 lyingbetween itandthe bottom or bed 31 of the wagon body. S'aid cross member 29 iss'pacedabove thebottom as clearly shown in 'Fig."15,.so that grain may pass outfrom beneath it when the panel is raised while still engaging behindsaid cross member.

The operation in this form is substan tially like that described as tothe other figures.

Having thus described my invention, I claim 1. An end gate including inits construction a pair of portions adapted to be detachably secured toa wagon box, cross members connecting them near their opposite ends inrigid spaced relation, creating an opening between them, a guide securedto the lower extremity of each portion near its edge adjacent theopening, and secured also to the lower cross member, said lower crossmember being spaced from the end of the bed of the wagon box, and aclosure for the opening lying between the spaced portions adapted toengage between said lower cross member and said bed.

2. An end gate including in its construction two portions, cross memberssecured to both of them connecting them at opposite ends in rigid spacedrelation, the lower of said members extending the entire width of thewagon box and lying rearward of and spaced from the bed of said wagonbox, and a guide secured to each portion near its lower extremitv, saidclosure engaging the guides and adapted at its lower edge to dropbetween the end of the bed'and said lower cross member.

3. In combination, a wagon body having a member extending across itsrear end below the bed thereof, said member having an opening extendingvertically through it for the discharge of materials, an end gateadapted for attachment to said body including an opening, a memberextending across the end gate across the last named opening spaced fromthe said bed and adapted to rest upon the first said member rearward ofthe described opening thereof, and a closure for the opening in said endgate adapted to seat between the said first member and the bed findoverlying the opening in said first mem- 4. In a device of the classdescribed, the combination with a pair of spaced members adapted to bedetachably secured to a wagon box, cross members near opposite endsspacing them in rigid relation, one of said cross members being spacedfrom the end of the bed of the wagon body, and a closure for end belowthe upper surface of the the opening between the members adapted to engae behind said mm ber between it and said waig'on bed, and able in itsown plan an the plane ct the spaced members, across extending rearwardlyfrom the we; bed below its upper surface up'on whic the lower'crossmembe is; adafted to the "said member een ingthe rear of the wagon bodyhaving a series of holes for the escape of grain lodging between thewagon bed and the first named cross member.
